/* ** ** Swift/XRT hardness ratio for Mrk 501. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 55659.462107 0.000466 0.23461 0.03672 0.97516 0 3.58554 0.24421 2.77245 0.18875 0.84120 0.11855 0.64745 0.09119 55659.462946 0.000373 0.31179 0.05073 0.98450 0 3.23032 0.25974 2.52675 0.20311 1.00718 0.14246 0.78871 0.11154 55659.463736 0.000417 0.25729 0.04112 0.98611 0 3.42293 0.24932 2.72510 0.19849 0.88070 0.12529 0.70173 0.09983 55659.464537 0.000385 0.27418 0.04404 0.96241 0 3.60450 0.26736 2.86770 0.21271 0.98830 0.14082 0.78599 0.11199 55659.465310 0.000388 0.26180 0.04198 0.98507 0 3.61506 0.26741 2.88323 0.21328 0.94642 0.13463 0.75489 0.10739 55659.466059 0.000362 0.30010 0.04845 0.95200 0 3.52433 0.27445 2.80398 0.21836 1.05765 0.14957 0.84174 0.11904 55659.466861 0.000440 0.21773 0.03426 0.98026 0 3.85509 0.25947 3.06893 0.20656 0.83935 0.11940 0.66876 0.09514 55659.468047 0.000747 0.38191 0.04083 0.96512 0 3.24029 0.18140 2.58031 0.14445 1.23750 0.11273 0.98509 0.08974 55659.469199 0.000405 0.29057 0.04716 0.96429 0 3.17198 0.24285 2.52796 0.19354 0.92170 0.13190 0.73426 0.10507 55659.469945 0.000341 0.31547 0.05244 0.99153 0 3.32021 0.27087 2.65740 0.21680 1.04744 0.15169 0.83831 0.12140 55659.470634 0.000347 0.27645 0.04424 0.99167 0 3.81927 0.28607 3.04269 0.22790 1.05585 0.14932 0.84174 0.11904 55659.471598 0.000616 0.30608 0.03742 0.99061 0 3.45154 0.20590 2.74379 0.16368 1.05646 0.11273 0.84007 0.08964
